Hand Filling

Pre-Filled Cartridges

Cartridges filled by hand by trained laboratory staff — a flexible route for custom formulations and smaller production runs.

How it works

From formulation to a finished product.

Cartridges are prepared, filled by hand under controlled laboratory conditions, closed with a stopper and deaerated. For pen + cartridge products, the filled cartridge is then assembled into the pen. Manual filling makes it straightforward to change formulation, concentration or volume between runs.

  1. 01

    Sterile cartridge unpacking

    Empty cartridges are unpacked in the laboratory, ready for filling.

  2. 02

    Cartridge filling preparation

    Cartridges and the formulated peptide solution are prepared for filling.

  3. 03

    Manual cartridge filling

    Laboratory staff fill each cartridge with the solution by hand.

  4. 04

    Stopper placement

    Each filled cartridge is closed with a stopper.

  5. 05

    Cartridge deaeration

    Air is removed from the filled cartridge.

  6. 06

    Final pen assembly

    For pen + cartridge products, the cartridge is assembled into the pen.
